| 摘 要： | 采用BAF工艺处理微污染含铁锰地下水,研究了其净化效能和适宜的运行条件.结果表明,在水力负荷为4-5 m3/(m2·h),气水比为3:1-4:1的试验条件下,BAF工艺能有效去除氨氮、锰、铁、CODMn.和浊度.当原水铁含量小于2 mg/L,滤层中部DO在4 mg/L左右时,对氨氮的去除效果最佳.微量Fe2+即可维系滤...

| Abstract: | The purification efficiency and optimum operation conditions of biological aerated filter(BAF) process,which treated micro-polluted groundwater containing iron and manganese were investigated.The results indicated that ammonia nitrogen,manganese,iron,CODMn and turbidity could be removed effectively by BAF process under hydraulic loading at 4 to 5 m3/(m2·h) and an air-water ratio of 3 ∶1 and 4 ∶1.The optimum removal efficiency of ammonia nitrogen was obtained when the iron concentration of raw water was lower than 2 mg/L and DO was about 4 mg/L in the middle of the filter bed.A small amount of Fe2+ could maintain the ecological situation of the filter bed and keep high efficiency of the manganese removal by BAF. |
